13 x 5.00-6 semi-pneumatic wheel suited to compatible zero-turn mower front castors, combining a slick tread with a 1/2″ axle fitment and central 148mm hub.
Suited to zero-turn mower front castors: Well suited to applications where the wheel needs to swivel regularly as the mower changes direction. The smooth tyre profile makes it a practical replacement option for compatible zero-turn mower front castor positions.
Slick tread helps reduce turf disturbance: The smooth tread has no aggressive lugs to bite heavily into the lawn, helping the castor pivot and change direction with less tendency to dig into or scuff turf during tight turns.
Semi-pneumatic cushioning: The semi-pneumatic tyre provides some cushioning as the mower travels across grass and uneven ground while avoiding the tyre pressure checks and inflation required with a conventional pneumatic tyre.
Low-maintenance tyre construction: With no air pressure to maintain, the semi-pneumatic construction is practical for mower applications where the wheel is regularly exposed to outdoor operating conditions and frequent turning.
1/2″ axle fitment: Suits a 12.7mm (1/2″) axle. Check the axle diameter on your existing mower wheel before ordering, as similar tyre sizes can use different axle fitments.
148mm hub length: The hub measures 148mm including the sleeve. Compare this measurement with the space between your mower’s castor fork arms to confirm suitable mounting clearance.
Central hub position: The hub is positioned centrally through the wheel. Check that your existing wheel also uses a central hub arrangement, particularly when replacing a wheel on an existing castor fork.
Commonly used on: zero turn mowers including Rover RZTS46, Cox Wright Stander X, and Hustler Raptor XD42.

Description
The SP13-500-500 is a 13 x 5.00-6 semi-pneumatic wheel suited to compatible zero-turn mower front castors and other lawn and mowing equipment. It combines a slick tyre profile with a central hub, 148mm hub length including the sleeve and a 12.7mm or 1/2″ axle fitment.
The slick tread is particularly useful on a front castor wheel because zero-turn mowers regularly pivot their front wheels when changing direction. With no aggressive tread blocks to grip heavily into the ground, the smooth profile helps the castor swivel across lawn and turf with less tendency to dig into or scuff the surface during tight manoeuvres.
Its semi-pneumatic construction also provides some cushioning as the mower travels over grass and minor surface irregularities. Because the tyre does not rely on conventional air pressure, there is no need for regular inflation or tyre pressure checks.
Fitment should be confirmed by measuring the wheel currently installed on the mower rather than relying on tyre size alone. For the SP13-500-500, check that your existing setup uses a 13 x 5.00-6 wheel, a 12.7mm axle and a central hub arrangement. The 148mm hub length including the sleeve should also be compared with the available space between the castor fork arms.
Using the universal wheel measuring guide alongside the product specifications can help confirm the important fitment measurements before ordering.
Product FAQs
Fitment should be confirmed by comparing the wheel with the one currently fitted to your mower rather than relying on the mower make or model alone. For the SP13-500-500, check the 13 x 5.00-6 tyre size, 12.7mm (1/2″) axle diameter, 148mm hub length including the sleeve and central hub position.
Also check that the tyre has enough clearance within the castor fork to rotate and swivel freely. The universal wheel measuring guide can be used to identify the main dimensions to check before ordering.
Start by measuring the wheel already fitted to the mower. Check the tyre or wheel size, overall tyre width, hub width or hub length, axle diameter and the available space between the castor fork arms.
For this model, two particularly important fitment measurements are the 12.7mm axle diameter and 148mm hub length including the sleeve. A wheel with the same tyre size may still use a different hub or axle arrangement.
A slick tread is well suited to a zero-turn mower front castor because the wheel needs to swivel as the mower changes direction. Without aggressive tread blocks gripping into the lawn, the wheel can pivot with less tendency to dig into or scuff the turf during tight turns.
The front castor does not require the same traction-focused tread pattern as a driven mower wheel.
The semi-pneumatic construction provides some cushioning as the wheel moves across grass and uneven ground without relying on conventional tyre pressure. This removes the need for inflation and regular pressure checks while still giving the wheel some compliance over minor surface irregularities.
This combination makes semi-pneumatic tyres practical for mower castor applications that see regular outdoor use.
A central hub means the hub is positioned centrally through the wheel rather than being offset towards one side. For the SP13-500-500, the hub length including the sleeve is 148mm.
When replacing an existing wheel, check both the hub position and hub length to make sure they match the mower’s castor fork arrangement.
